The Kenny Brown GT4-S is a premium performance Mustang with 650 “Nail You to the Seat” supercharged horsepower, specifically designed with speed and agility in mind. The GT4-S easily outpaces the Shelby GT500 at track days, but the awesome power is only part of the performance equation.

It's lighter, quicker, and more responsive than a Shelby GT500, or even the fabled Super Snake. As with all Kenny Brown Mustangs, there is an artful balance of power, grip, handling, and braking in the overall performance package. A large part of that equation is the critically acclaimed AGS 4.0 Advanced Geometry Suspension System which is the “secret sauce” in the car's incredible handling and confidence-inspiring driving characteristics. But it doesn’t stop there as additional upgrades include bigger brakes, wider wheels, large sticky tires, high-flow exhaust, and a host of other select upgrades to balance out the wickedly fast GT4-S Mustang. And as always – Kenny offers a plethora of performance options to truly make it your very own bespoke creation.

The new 2013 Kenny Brown GT4-S Mustang is the most powerful to date with a 0-60 acceleration time and sheer cornering grip that rivals the industry's best. Never in the company's history has such a potent Mustang been unleashed on the general public, and we have Ford's awesome new 5.0L TiVCT powertrain to thank for that.

Yes, a super-fast, supercharged GT4-Sa Mustang with an Automatic. Until now all supercharged Kenny Brown Mustangs have come only with manual transmissions. But the new 6-speed automatic transmission in the 2013 Mustangs has changed the equation, and Kenny’s thinking, providing you all the excitement with just two pedals.

The GT4-S automatic Mustang is designed primarily as a wicked fast street car, but it feels right at home on the track. With a healthy 610 supercharged horsepower and all the carefully selected equipment that makes it a dream to drive. The automatic combined with traction control make it a brilliantly quick, yet amazingly civil car just driving around town. This is the kind of Mustang that you can seriously spank a Viper with at the toll booth grand prix - with a cup of coffee in your hand. If you're feeling really sporty, click the traction control into Sport Mode, drop the shifter into Select, and unleash the beast. The SelectShift lets you select gears up and down manually with a touch of a button, and the traction control in Sport Mode gives you tire smoking capability, but you had better be hanging on to the steering wheel and forget the coffee because this speed monster demands respect.
